Nukufetau is an atoll that is part of the nation of Tuvalu. The atoll was claimed by the US under the Guano Islands Act some time in the 19th century and was ceded in a treaty of friendship concluded in 1979 and coming into force in 1983. It has a population of 536 who live on Savave islet. In 1951 the school that was located on Motumua islet was transferred to Savave and became the government primary school for Nukufetau. It was named the Tutasi Memorial School in honour of its predecessor.
